Un r irrnia r nine ,ASSIGNOR TO LYBAPHONE COMPANY OF AMERICA, OF WASHINGTON, DISTRICT OF COLUMBIA, A' CORPORATION OF DELA WARE.

T (177 whom, iz' may concern lie it known that I. Main; JAY Snmnns, a citizen of the Tnitcvl States. and a rcsivlcnt Ofil1P-bOYOllgll of Manhattan, city, county, and :State of New York. have invented ccrlain'ncw and useful Iinprovcnicncs in Talk Jig-Machines, of which the following is. a

ncicification i One object of my invcniion is to provide a"ca'lking machine which shall he comparat ivcly incxpcnsivc in inanufactum. and at ihe'saine tiinc pleasing in appcarancc and cfiicient in operation.

Another object of in invention is to prowhich will cli' cct a rruc; pure and accurate reproduction of toncs or sounds. without i110 production of gihc false. harsh noises so oftcrr llfiili'wl in i'theaoperation of instruments, of (his character. 1 Q

Another object ol H1) invcntion is to incrcasc e volume of soumi emitted. by con- .strucli.ng thc cnliil'c case and lhc sounil aniplificrof shect inctai, and by so conncciting "Thcsc parts thai he casc will vihratc in unisonwith the ainpiiiici:

w'r rnoilicr o jcct of my invention is to construct tin? ni'l aniplificr in such a way that .it' will have the requisite stability and at thev same time *ill be l(-21(illi{ rcsponsivs to ,ihi'ations of various frequencies.

Siiil anothcr object of my invcntion is to proviflc air cushions forihc vibrations of tho amplifier, anil thus ciiniinatcall harshness of tone.

Other objects and advantages of my iniprovcd (lcvicc will he pointccL mob in the specification and claims which follow.

as. is cicarlv shown. Means such as the hannllc ll niav be provided for winding the m0- tor. and a suitable braking mec sn1 such as indicated at 12 may be emcployecl for coni'roliing the rotation of the rhcord supporting'vlisk in a manner which is Well understood. v

Thc sound box 13 is provided with'tha usual stylus 1i, which is adapted, when the device is in opcra'tion, to rest upon a record supported-h the disk 9. The sound box 13 may he conn'ccted to theoxtension 15 ofthe sound amplifier 16 by any suitable tone arm 17. I prefer; however, to employ a flexible tone arm which is adapted to be connected to the extension 15 by a pin and slotconnection such as is indicated at 18, suclra tone arm anrl such connecting means being fnily (inscribed in my co-pemling application, Seriai Xuinhcr 62,979. fiiecl November 23, 1915.

The souml amplifier 16, which is of: subaniiallv rccianguiar gradually increasing cross section, is constructed of sheet metal,

inc mal'crial heing pr'cfcrahiy the same as that clnplovcd Tl oi tho casing ihcrci'o a2 ilug hv iiliriHSillQ unison. in ofihc' ainl conn ciing i'he ain'plifieranci casing, 1 cause tho-entire casing to vibrate as a sound- (i. and thus obtain a sound. reproduction of grout vol'uine.

it is evident that walls of the amplificr 16 were merely plane surfaces, they \vonid lack the stability "req- Hisil'c to the iccurat'e vibration thereof, 1 have there-fore ci'mcciverl ihirida ofboiving or buckling these surfaces as shown in Fi n and i find that by thus maintaining the mater i l or the amplifier under a certain clegree of sf ress I eliminate all raise vibraiions thercoi As a mcans. for insuring tho accnrate vi: hration of the amplifier; I preferably pro vicle the top and bo't tom Wa lis thereof with stiffening such as are indicated at 19, :20, 21. These ribs are formed by indenting as shown, and is connected rcar anci zit-rho iront Wherearul the amplifier vibrate 1n the waiis from Within and has severa ribs in constructing the casing ac annihficr is iocated within ihe base 5- words, by so constructing if the, top ancl bottonr the rib 20, may ex va single embodiment of my invention, it will I lengths,

wall, and the rib 21 may be substantially the same as rib 20, except that it is located nearer the edge and is of less length. By providin these ribs of various forms and I find that the amplifieris rendered more readily responsive to vibrations of various. frequencies, or, in other words, the

' accurate reproduction of both high and low ponent' surfaces. or soundin tones is insured. The-principle on which suchan amplifier operates is somewhat similarto theprinciple'of operation of instruments of the type of the violin. Such instrumentsl-jare{practicallyalways provided with S-shaped recesses in their ll'pper surfaces. These recesses divide. the su aces into comboards of various lengths, whereby the vibration thereof atvvarious frequencies is'facilitated. p

p order to obviate the possibility of any harshness in the tones reproduced, I preferany surround the amplifier with confined airj spaces. These-spaces serve as cushions forthe vibrations, and thus eliminate all harshness- I preferably form these air spaces by fitting, within the casin above the am ,lifier, a iece .ofcorrugate material, sli' j gas paste, and, as indicated at 22 in the drawing;- This piece of material, in addition -toijit's fi inction of inclosing the air spaces,

operates also .as' a 'sounding board, and becaus 'ofits texture-servesto soften the tone emitted. 1 i

It is a' parent froml'the foregoing that I have pro uceg'lfa scientifically constructed instrument wlrielrwill truly and accurately reproduce vocal as" well as instrumental music,

,and..,1vill;,dof so without the harsh, nasal often noticed in the operation of n triiments of this character. -Wh 'ileI have illiistrated and described but be obvious'to those skilled in the art, that man' y chanfges may be made; therein without departing rom the spirit of my invention.

casing, a metallic sound amplifier-also inclosed ..within and secured to said casing, whereby the casing vibrates in unison with the amplifier, and a sheet of corrugated material fitted within said casing between the motor and the amplifier, whereby said amplifier is surrounded by a confined air space, and is acoustically insulated from said motor, for the purpose described.

3. Inadevice of the kind described, a casing, a motor contained therein, a sound amplifier passing through the casing beneath the motor and a sheet of sound insulating material extending wholly across the casing and interposed between the motor and amplifier.

4. In a device of the kind described, a

sound amplifier passing through the casing,

a casing having an aperture in its upper side, a cover adapted to completely cover said aperture, a motor suspended from said 'cover and a sheet of sound insulating material extending across the casing beneath the motor and separating the motor chamberfrom the amplifying chamber. 2
